This site is located 2 miles north of Del Norte, Colorado in Rio Grande County. I, Stephanie <br />Mitchell of the Colorado Division of Reclamation, Mining and Safety conducted the inspection. Mr. Todd <br />Stokebrand of Asphalt Constructors, Inc. accompanied me on the inspection. <br />This is a 66.54 acre 112c mining operation for sand and gravel with a maximum allowed disturbance of 30.49 <br />acres. The current disturbed acreage is appears to be right at 10 acres. The Division currently holds a financial <br />warranty amount of $70,121.00 for this site and is adequate at this time. <br />A mine identification sign was in place at the entrance to the mine site. All permit boundaries were all clearly <br />marked delineating the permit area. <br />Mining is currently taking place in the Phase III of the permit area, moving north and west. The staging, <br />process and stockpiles are located in this area as well. <br />Material stockpiles appear to be stable. There are about 5 material stockpiles located in the staging area. <br />There is a very large population of Spotted Knapweed and Kochia within the permit area. This is noted as a <br />problem at the beginning of the inspection report. The Operator must combat invasive weed species per Rule <br />3.1.10(6). <br />Fuel is being adequately stored with secondary containment. A scalehouse, 936 CAT Loader, Screener, Crusher <br />and portable Asphalt Plant were located on site. <br />An Asphalt Stockpile was on site. The Operator does not plan on burying, but uses it for binder in rock <br />products. <br />Responses to this inspection report should be directed to Stephanie Mitchell at the Division of <br />Reclamation, Mining & Safety, Grand Junction Field Office, 101 South 3rd Street, Room 301, Grand <br />Junction, Colorado 81501, phone number 970.242.5025. <br />Page 2 of 6 <br />
